Is the word doenças the same in Brazilian and European Portuguese?

Yes

The word "doenças" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference is in pronunciation.

In Brazil, the "s" at the end of the word is pronounced as a soft "s" (like the "s" in "sun"). In Portugal, this "s" is palatalized, meaning it sounds like "sh" (like the "sh" in "shoe"). Additionally, Brazilians tend to pronounce vowels more openly and clearly, while Portuguese speakers often "swallow" or reduce unstressed vowels, making the word sound more closed and compact.
